Ultrafast Silicon for the 100 GbE future

• VEGA signal Converters

Micram VEGA converters are single-chip SiGe solutions with a scalable open architecture for direct conversion between analog and digital domains (ADC & DAC) that allow for sampling rates in excess of 25GS/s. They are built using a library approach that allows for quick adoption of application specific requirements.
The VEGA DAC 25 is a digital to analog converter, a demonstrator IC proving the inherent performance and functional capability of our modular approach (6 bit, operating up to 30 GS/s with an analog bandwidth of 25GHZ). The demonstrator is available on an evaluation board.

Our next converter is the VEGA ADC 30, a 6 bit Analog Digital Converter designed for 30GS/s. Two chips can operate in interleave mode to achieve a sampling rate of 60GS/s at an unseen bandwidth of 20GHz. Further on the roadmap is a single-chip converter chipset for 60GS/s.

• VEGA Early Silicon Program

Micram VEGA is a family of ultrafast SiGe-bipolar silicon that enables visionary researchers and product development engineers to move aggressively on their 100 Gigabit Ethernet projects today – not years from now.
VEGA signal converters deliver 30 GS/s sample rates at 15 GHz – full 100GbE bandwidth, today. By the time others achieve this performance, VEGA will be delivering 60 GS/s at 15 GHz bandwidth.

Micram is a small, highly focused development team that has realized many significant technical achievements over its long history. With the extraordinary performance of VEGA, we have an opportunity to join with select customers to define the future of ultra-high speed networking.

• Micram RF Modules

For Fiber-Optical Prototyping and Measurement Applications

Micram RF Modules provide a convenient and effective means of implementing Micram silicon in a test lab environment. Originally developed for internal use, Micram RF Modules eliminate time-consuming configuration work and provides a stable, reliable chip mount with easy access for any kind of test equipment.

For years, the Micram engineering team dealt with the many problems of building custom measurement rigs for its High-Speed Measurement Laboratory. Hours of soldering and fitting cables often resulted in poor performance and inaccurate measurements due to the lack of stable accessory components, such as suitable standardized connectors and provision for cooling, as well as signal reflections and signal losses caused by rig assembly and configuration problems.

After much experience, thought and discussion, the Micram team created a special mount for Micram chips under test, using brass modules and suitable high-frequency substrates and providing easy signal access through standard K-connectors.

Test and measurement of high-speed fiber-optical systems requires a range of capabilities: multiplexing to generate extremely high bit rates (up to 100 Gb/s), de-multiplexing to enable lower-performing oscilloscopes to measure performance, clock and data recovery and clock phase shifting. Micram created RF Modules for each of these functions and now offers them for use in other labs.
